Volume Calculator
Calculate the volume of various 3D geometric shapes and solids
Select a 3D Shape
Cube Volume Calculator
A cube has 6 equal square faces. All edges are the same length.
Cube Examples
Side: 1.5 cm
Side: 50 cm
Sphere Volume Calculator
A sphere is a perfectly round 3D shape. Every point on the surface is equidistant from the center.
Radius = Diameter ÷ 2
Sphere Examples
Radius: 12 cm
Radius: 6.371 million km
Cylinder Volume Calculator
A cylinder has two parallel circular bases connected by a curved surface.
Cylinder Examples
Radius: 3.3 cm, Height: 12 cm
Radius: 30 cm, Height: 90 cm
Volume Calculation Tips
Always use the same units for all measurements. The result will be in cubic units (e.g., m³ for meters).
For precise calculations involving π, use more decimal places (π ≈ 3.14159265359). Calculators typically use high precision.
Volume calculations are useful for liquid capacity, material estimation, shipping, and storage planning.
Remember: 1 m³ = 1,000 L, 1 ft³ ≈ 28.3 L, 1 in³ ≈ 16.4 mL. Use conversion tables for accuracy.
For irregular shapes, break them into simpler forms or use water displacement method for physical objects.
Volume × Density = Mass. Use this relationship to calculate weight when you know volume and material density.
